The species occurs in scattered areas along the Utah-Arizona border, from the vicinity of Fredonia, Coconino County, to an area south and southeast of St. George, Utah in Mohave County, Arizona and at a few places in Washington and Kane County, Utah. It occurs at elevations of 900 to 1,600 m asl.

The main threats are gypsum strip-mining, ORVs, grazing and trampling animals stepping on plants, overcollection, and mining. However, these threats are mitigated in part of the range by management plans. The Utah population could be impacted by the Warner Valley Power Project.
